"This is a great value lens, and in my opinion can't be beat for the price. I photograph everything from wildlife to portraits to flowers and macro shots to landscapes. While this is not a do all lens, it fits right in and works for anything that fits within its 50-200mm zoom range. The build quality is also exceptional at the price, with no slop in the workings of the lens. It also comes with a lens hood that conveniently stores backwards on the lens. The focus is internal, so it good for polarized filters, tulip hoods, etc. All in all a great lens for the price."
